I love shellfish Larry. Lobster, clams, shrimp, crab. I just can't stomach the fishy smell and taste of almost all fish. I do like fresh caught brook trout, fried smelts, and fried calamari though.
Well I LOVE black licorice, Could eat bags of it. Now I dislike a bunch of stuff, but my very worst thing would have to be sauerkraut. I woun't even let the wife cook it in my house, and she likes it.LOL Makes me sick just to smell it.
Liver! From any animal or bird. Don't care much for any filtering organ...
Tried balutes, monkey, sea urchin, eel, and many other 'exotics' from around the world. Might not try some of them again, but all were more palatable to me than liver.
